y LIFTING-POWER.

l To all whom it may concern.:

Be it known that I, JOHN M. RoiiiN, a eiti' zen of the United States, residing at Klamath Falls, in the county of Klamath and State of Oregon, have inventednew and useful lin rovemen'ts in Lifting-Power, of which the fb owing is a specification.

Tltis invention relates to lifting apparatus of that type in which horse power is employed hereby water can be lifted from wells or other sources and discharged into irrigating ditches, by which earth can be removed from ditclzes, cuts or tlte like or whereby heavy objects can be raised in a simple, eflicient and' inexpensive manner.

Tne invention has for one of its objects to improve and simplify the construction and roperation of apparatus of this character so as to be comparatively eas and inexpensive toinanufactui'e and insta l, thoroughly re-- liable in service, and readily controlled.

v A further object of the invention is the provision of lifting apparatus composed of an oscillating cage or pen in which one or more horses or other animals are adapted to be driven from end to end thereof to thereby cause the cage to tilt for the purpose of alternately raising buckets or other suitable load-- cari'Y ing devices from which tie contents can edelivered at any suitable point.

A further object of the inventioi is the provision of a lifting device of the character referred to in which the cage is mounted on a turn table so that the buckets or letal-carrying devices can be moved back and forth between the point of loading and point of discharge, as for instance, in loading` earth from cuts, ditches or the like, to dirt cars.

Another object isthe ein loyment of means whereby the bucket-s or ond-carrying devices can be raised step by step' by tire os cillation of the cage tor lifting heavy loads,

the said means being so designed as to permit the empty buckets to be 'quickly lowered to the oints of leading.

provision of a controlling mechanism for permitting the operator to control tite speed of the oscillatory movement of tbe cage.

[an additional object is to provide lifting buclets having means for permitting an e3;- eessive amount of material to be discharged from the bucket, should the original load be greater thanfthe power of the apparatus.

With these objects in view and others, as Wili appear as the -riescription proceeds, the

Specification of'Lettei's Patent.

Fig. 6 is a detail sectional view of one vof trie lifting buckets.

Similar reference characters are employed to designare corresponding parts throughout the several views. s

ln the present instance, l have elected io illustrate the invention as a if-.Ltcr-lifting de- 'g vice, but ir is obvious that it may be used for 'y many other purposes u'licu material is to be lift-.ed from one point to another.

Referring', to the drawings, A designates a supporting'` frame composed of a base l, uprights 2, and a platform 3 on which is arranged a circular track 4, the supportingl structure being located between the wells B and 'BC Mounted on their-ame A is a turntable C prrwided with wheels 5 at diametrirally opposite points resting on the circular track 4, and rising from the turn-table are spaced standards between which is disposed an oscillatory structure D in the forni of a cago or pen and comprising a liooi' 7, a railingl rl, and central upright posts 9. At the middle of the cage and extending oppo- ,siely from the lloor thereof are horizontal pivots l0 journalcd in tho standards (i, as 1 clearly shown in Fifi'. for piyoially mountingr the cage l). 'l he ends of the cage4 are formed inio gates ll hinged ai l2 tothe sides of the cago so that the horses can be driven into and oui of the rage. Extending be- 1 ineen and secured ro the corners of the cage and ihr upper ends oi the posts (d are brace rods iii for giving' rigidity to the structure. g By mounting the cage in this manner, it is 'i capable of having an oscillatory movement l on a' horizontal axis formed by the pivots l0 l and of a turning movement about theverl tical axis of the turn table C. On the base hereinafter and set forth with particularity Fig. is a 1 may be fprovided rollers 1 which run on tracks 1b or permitting the apparatus to be moved from point to oint. Under the ends of t 1e cage are buckets or 5 loading devices E and E ofany approved form, which are attached to the ends of separate cables e and e. These cables are connected with a winding device designated generally by F, whereby the oscillatory movement of the cage will raise the buckets step by stepffrom any depth. The cables project through openings 14 in the Hoor of4 the cage adjacent the ends thereof, one of l which o 15 Dispose at suitable intervals along the cables are stop devices 15 preferably in the form of collars that taper upwardly and which coperate with clamping devices arranged at the openings 14. Each device consists of a stationa jaw 16 and a springmovable jaw 17 whic yields in a direction away from the fixed jaw when a collar engages the same as the cable is `pulled upwardly, and s ringing inwardly to coperate with the fixe jaw for engaging under a collar' 15 to prevent the cable from being drawn downwardly through the opening by the Weight of the bucket and its contents. The spring jaw 17 of each cableclamping device is extended into a foot piece 18 whereby the operator can spring the jaw to one side when it 1s desired to permit the empty bucket to be lowered by the cable to the place of loading.

' The winding device F comprises a pair of drums f and f loosely mounted and s aced a art onl a horizontal' shaft 19 journa ed in .t e standards 6 adjacent the up er ends thereof. The opposed ends of the rums are formed into reversely dis osed ratchet teeth 20 which engage with rate et teeth 21 formed on op osite sides of the disk 22 that is s line on thevshaft 19, as clearly shown in i 3. The disk or element 22 i-s adapted to sli e on the shaft 19 so as to be automatically engaged with the teeth'of one drum and disenga ed from the teeth of the other drum by the a ternate rocking movement .of the shaft 19. In other'words, the drums f and f', to which the cables E and E are respectively ste so that the cables can be wound thereon an the buckets elevated.

It is to be noted that suflicient clearance is provided between the disk 22 and the drums f and f so that the teeth at one side of the clutch element 22 will engage the cor--A responding teeth of one drum, while the teeth 21 on the opposite side of said element disengage ythe teeth of the other drum. During the initial part of the movement of the shaft 19 in either direction, the clutch element 22 will be shifted, by reason of the shape of the ratchet teeth, from one' drum to the other,

which is thereby clutched tov the shaft to' move therewith. For actuating the shaft enings is clearly shown in Fig. 4.'

connected, are alternately rotated step by l on which the cage oscillates, and since the shaft 19 is relatively stationary as compared with the cage, the cable 24 will cause the spool 23 to be turned alternately back and forth withthe oscillations of the cage. As one cable is wound on its drum, the other cablel is prevented from unwinding because the vstop device 15 therefor sustains the weight of the load-car ing device attached toA such cable, so that llttle, if any, draft on the cable exists to cause unwinding thereof. It Will thus be seen that the buckets or loadcarrying devices E and E will be raised step by 'step by the winding device F until the buckets have been raisedv clear of the wells. After this oint is reached, the horse or horses can se stopped at the center of the cage so that the latter willbe perfectly` bal anced in a horizontal position Ifor.thep'rpose of permitting thejcage'to beturned for carrying iirst one bucket to a point of convenient unloading, and then the other bucket. After the buckets have been thus unloaded, the cage is turned back to its original posltion and the buclilts permitted to descend into the wells for a second filling. To do this, the spring jaws 18 are released from the cable and they can be held released by suitable devices, such for instance, as links 26 attached to the door, and which can be thrown over the extremities of the jaws, as will be understood by reference to Fig. 4. For preventing the buckets from descending too rapidly, a brake device is provided with each drum so as to retard' the unwinding of the cables. For this purpose, a brake lever 27 is fulcrumed above each drum on a'shaft 28 and the loweri end ofthe lever is provided v with bifurcations 29' forming shoes for gripping ithe concaved portions 3() of the adjacent drum. The upper end of each brakeV lever is connected by a rod 31 with an oper'- ating lever 32 fulcrumed at 33 on one of the standards 6, so that by manipulating the' lever, one or the other of the bifurcations or brake shoes can be thrown into grippin relation with the drum. :The .buckets ar adapted to be. lowered one at a time so that after the operator controls the lowering of a bucket by one operating lever 32,'he crosses to the opposite side of the cage and lowers the other bucket by the other lever 32. f

A brake device is provided for the purpose of permittin the operator to prevent the cage 'from ti ting too rapidly, and for thisv ur ose, the shaft 19 is equipped with a ra e drum 34 adjacent the spool 23, and voted at 35 on one of the standards 6 is a Erake lever 36 having its u per end bifurcated to span the drum or engagement cage is prevented from tilting toofast.

therewith at opposite points. The lower end of the brake lever 36 is connected with the rod 37 extending longitudinally of the cage adjacent one side thereof and arranged with the middlcportion bowed outwardly around the front standard 6, while the extremities are disposedwithin the cage. The extremities of the operating rod 37 are provided with spaced levers 38 fulorumed at 39 on the sides of the cago so that the operator can actuate the rod 37 from different points within thc cage, the lower ends of the levers being connected With the rod so that by moving any lever in one direction or the other, the rod will be shifted longitudinally and the brake lever 36 tilted so that one of its bifurcations will frictionally grip the brake drum 34 and thereby retard the rotation of the shaft 19, with the result that tlIie n other Words', when any lever 3S is pulled to the right, Fig. 1, the rod 37 will be shifted to the left and tilt the brake lever 38 so that the left bifurcation thereof will frictionally engage the brake drum 34 and prevent the cage from tilting suddenly. If any brake actuating lever 8S is tilted to the left, the rod 37 is moved to the right to'correspondingly tilt the brake lever 36 for causing the right bifurcation of the latter to frictionally' engage the brake drum 34 and retard the tilting movement of the cage.

In the modification shown in Fig. 5, the cage D is mounted to oscillate on a fixed frame G, and the operating mechanisms are similar to those described in connection With bles and winding drums are employed. The

4buckets E and E are suspended by means of links or rods 40 that are hingedly connected at 41 with the bottom of the cage. Located in the path of each Vbucket is aV bucket-turning device 42 which engages the top' of the bucket as the latter is raised so that the latter Will Lbe turned on its bail 43 so `as to empty the contents into a trough er other device 44, as shown at right hand of'- Fig. Should the load in either bucket be greater than the lifting power, provision is made for permitting part ofthe contents to be discharged, and to this end, each bucket has an opening 45 in its bottom as shown in F ig, 6, which is normally closed by a valve 46 hinged at 47, and attached to thevalve is a ilexible element or cord 48 that passes upof the cage sothat it can be grasped by the operator for` permitting the valve to be opened to let out part of the contents of the bucket. It will thus bessen that the overloading of the buckets can be easily and effectively prevented so that the-operationy of 'From the foregoing description, taken in wardlyl through an opening 49 in the floor 7:
